John is a system administrator. He works remotely and charges by the hour. The customer doesn't understand John's job. So John takes a few minutes to write a file named jobToDo, containing all the lines that he'd normally have to enter in the Shell for his job. Then, he writes a script doMyJob.sh that schedules all the lines to be run, waiting for 5 minutes between each line. So for example, the first line runs now, 5 mins later the next line will run, etc. John wants to start the script and go play at the Casino while charging the customer for 5 hours worth of work.

Write the script to help John enjoy life. To run a line, give it as argument to exec.
